T/SCSX 0801-2023 Double Wall Strength-Rated Ultraviolet Stabilized Polyethylene Geogrid (UPE-T) Reinforced Piping Casing Specification for Buried Applications

Scope

Main technical content: This standard specifies the terms and definitions, symbols, abbreviations, raw materials, pipe grading and marking, pipe structure types and connection methods, technical requirements, test methods, inspection rules and markings, transportation and storage for modified polyolefin (UPE-T) double-wall reinforced winding pipes used in buried applications. This standard applies to double-wall reinforced winding pipes made from modified ultra-high molecular weight polyolefin (UPE-T) resin as the main raw material. The raw material is melt-extruded into trapezoidal strip by an extruder, then heat-welded and reinforced by a co-extrusion process. The welded joints are equipped with anti-slip buckles. This product features high ring stiffness, strong shear resistance, good ring flexibility, easy flexible installation, strong water flow capacity, good chemical performance, good cold resistance, excellent wear resistance, light weight, and good economy. The pipes specified in this standard are suitable for long-term transportation of various chemical media, and do not react with general weak acids, weak alkalis, or salts. They can be used in non-pressure buried drainage and sewage projects with an ambient temperature range of 40℃ to -60℃.
